Model's indexes aren't updated

[DalerAkhmetov]

Hello.
If model of previous state have no indexes and i will add index in this model then i will still get message "No changes found".

I found bug. Could you fix this code section:

        if (models[model].options.indexes.length > 0)
        {
            let idx_out = {};
            for (let _i in models[model].options.indexes)
            {
                let index = parseIndex(models[model].options.indexes[_i]);
                idx_out[index.hash+''] = index;
                delete index.hash;
                
                // make it immutable
                Object.freeze(index);
            }
            models[model].options.indexes = idx_out;
        } else {
            models[model].options.indexes = {}; // Important change, because models[model].options.indexes is [] but it must be {}
        }
        
        tables[models[model].tableName].indexes = models[model].options.indexes;
